I think the point of this is that the only people fooled will be the people who want to be fooled, and everyone else will just be annoyed. For instance if I said I grew up in the woods, and didn't have any woods skills, I would look like an ass. And though its not true all of the time, people who grew up poor tend to be able to improvise pretty well, since they had to figure stuff out on their own, or to tough things out, or a combination of the two. Its nice to know if someone will be a help to you before you travel with them, instead of being misled by a wannabe.
I'm not poor anymore, I admit that, but squatting and working full time for a few years does that to you.
